In particular, a wind-power-installation tower segment for a wind-power-installation tower, comprising a shell segment, having an extent in the direction of a segment height, a segment ring direction and a segment thickness, and an upper horizontal abutment side and a lower horizontal abutment side, a holding device for arranging requisites inside a wind-power-installation tower segment, having a main section, and at least one projecting section, wherein the main section and the at least one projecting section are arranged adjacently to each other in the segment ring direction, wherein the main section and the at least one projecting section enclose a holding-device angle, a coupling device, which is arranged in a coupling section of the shell segment, adjoining the upper horizontal abutment side, wherein the holding device is coupled to the shell segment by means of the coupling device. ## Claims ### Claim 1 A wind-power-installation tower segment for a wind-power-installation tower, comprising: a shell segment, having: a segment height, a segment ring direction, and a segment thickness, and an upper horizontal abutment side and a lower horizontal abutment side, a holding device for arranging requisites inside a wind-power-installation tower segment, having: a main section, and at least one projecting section, wherein the main section and the at least one projecting section are arranged adjacently to each other in the segment ring direction, and wherein the main section and the at least one projecting section enclose a holding-device angle, a coupling device arranged in a coupling section of the shell segment, adjoining the upper horizontal abutment side, a vibration damper, and a horizontal bearing, wherein the holding device is coupled to the shell segment by the coupling device, wherein the vibration damper is arranged and configured to damp vibrations orthogonal to the segment height or in a direction of main extent of the holding device, or both, wherein the horizontal bearing comprises the vibration damper, and wherein the vibration damper comprises one or more plates bearing against the holding device, wherein the one or more plates are a plastic material. ### Claim 2 (depends on 1) The wind-power-installation tower segment as claimed in claim 1, comprising a horizontal bearing arranged in a bearing section and adjoining the lower horizontal abutment side of the shell segment, wherein the holding device is supported by the horizontal bearing, and wherein the horizontal bearing is configured to act: as a fixed bearing for bearing forces orthogonal to the segment height, or to a to the direction of main extent of the holding device, or both, or as a loose bearing for bearing forces in the direction of the segment height, or the direction of main extent of the holding device, or both. ### Claim 3 (depends on 1) The wind-power-installation tower segment as claimed in claim 1, wherein: the coupling device is arranged and configured to couple the holding device to the shell segment in such a manner that the direction of main extent of the holding device is oriented substantially vertically, and the coupling device is arranged on the holding device and configured to act as a fixed bearing for forces acting in a direction of the segment height or the direction of main extent of the holding device, or both. ### Claim 4 (depends on 1) The wind-power-installation tower segment as claimed in claim 1 comprising a ladder arranged on the main section. ### Claim 5 (depends on 1) The wind-power-installation tower segment as claimed in claim 1, wherein the at least one projecting section comprises a first projecting section and a second projecting section, wherein the first projecting section is arranged on a first side of the main section, and the second projecting section is arranged on a second side of the main section that is opposite the first side. ### Claim 6 (depends on 1) The wind-power-installation tower segment as claimed in claim 1, comprising at least one cable arranged on the at least one projecting section, and wherein the at least one cable is spaced less than 1.5 meters from the main section. ### Claim 7 (depends on 1) The wind-power-installation tower segment as claimed in claim 1, wherein the holding-device angle is less than 170 degrees of arc. ### Claim 8 (depends on 1) The wind-power-installation tower segment as claimed in claim 1, wherein: the shell segment has an axis of symmetry, and the holding device extends from an upper holding end to a lower holding end. ### Claim 9 (depends on 1) A wind-power-installation tower comprising at least one wind-power-installation tower segment as claimed in claim 1. ### Claim 10 (depends on 9) A wind power installation comprising the wind-power-installation tower as claimed in claim 9. ### Claim 11 (depends on 1) The wind-power-installation tower segment as claimed in claim 1, wherein the holding-device angle is between 170 degrees and 145 degrees. ### Claim 12 (depends on 1) The wind-power-installation tower segment as claimed in claim 1, wherein the holding-device angle is less than 145 degrees. ### Claim 13 (depends on 1) A method for assembling the wind-power-installation tower segment as claimed in claim 1, the method comprising: raising the holding device by at least three transport elements, wherein the at least three transport elements are arranged at a fastening point of a lifting mechanism, and wherein the at least three transport elements are arranged at at least three fastening points of the holding device, wherein at least two fastening points of the at least three fastening points are spaced in the direction of main extent of the holding device, and at least two fastening points of the at least three fastening points are spaced in a width direction, arranging the holding device on an inner circumferential surface of a shell segment, and coupling the holding device to the shell segment using a coupling device. ### Claim 14 (depends on 13) The method as claimed in claim 13, comprising: arranging the at least three lifting elements between a crosshead and the holding device, and wherein the lifting elements are arranged, on the crosshead, at at least two crosshead fastening points, wherein the two crosshead fastening points are spaced from each other in a longitudinal direction of the crosshead. ### Claim 15 (depends on 1) A method for assembling a wind-power-installation tower section, the method comprising: arranging the wind-power-installation tower segment of claim 1 and a second shell segment in such a manner that the wind-power-installation tower segment and the second shell segment abut against each other at vertical abutment sides; and fastening the wind-power-installation tower segment and the second shell segment to each other.
